SD / eMMC performance

You can boot from a MicroSD card or an eMMC module. The microSD interface also supports higher performance UHS-1 mode.

File access for a 512 MB file (read / write) on three different storage options shows clear performance losses.

EMMC 5.0 storage is ~ 7x faster than the MicroSD Class-10 card in read tests. The MicroSD UHS-1 card is ~ 2x faster than the MicroSD Class-10 card in read tests. The MicroSD UHS-1 card provides a good price option for many applications!
